White Paper: Linear Bearings and Guide Bar Designs for Fitness Equipment

SPONSORED BY:

As the field of specialized fitness equipment has grown, so has a proliferation of various designs and configurations for both the equipment and their guide mechanisms. The fastest growing segment of focused equipment are those designed to meet the needs for smooth consistent motion and feel. Typical bearing options for this specialized equipment include linear rolling element bearings, bronze bushings, solid plastic bearings, and Simplicity self-lubricating bearings.

In this paper, we discuss the various components and basic requirements needed in weight stack and fitness equipment applications, along with the advantages and disadvantages associated with each type of bearing option. In addition to consistent smooth motion, weight stack needs require repeatable tolerances, ease of assembly, and a minimum amount of maintenance.

The patented self-lubricating Frelon® liner in Simplicity bearings provides consistent results in all the required areas. The quality and repeatability of fit and function are present throughout the entire manufacturing, assembly, and usage life cycle.
